Young scholars examine the causes and effects of soil runoff. In this environment lesson, students look at ways in which soil runoff is controlled. Young scholars then play a game  and discuss how the Peace Corps deals with soil...

Investigate the amazing ability of plants to filter contaminants from water with this series of in-class demonstrations. After placing six small, potted plants in plastic cups, different solutions and mixtures are poured into them that...

Young scientists study the construction of a battery through experimentation. They engage in five experiments which combine to create a thorough study of the history of batteries beginning with a model of the first battery.

In chemistry, organic means something contains a carbon base. A helpful presentation starts by defining macromolecules as large organic carbon molecules. Scholars answer questions about each topic on the associated worksheet. It covers...

Candy is one of my favorite words, and it's an even better word when it relates to science. Yes, candy science can happen when you grow rock candy crystals with your class. The entire process for growing these edible wonders of nature is...

In this biology worksheet, students examine the transport of gases in the circulatory system and how they bond to hemoglobin.

Learners conduct a scientific investigation about the formation of stalactites and stalagmites. They conduct an experiment to reproduce them in the lab environment. Students make observations over a period of time in order to see the...

For this organic reactions worksheet, students are given descriptions of the seven types of reaction of organic compounds. They then answer six questions about these reactions.

In this molecular model learning exercise, students use a molecular model kit to construct 13 different molecule models. After constructing the molecules, the students complete 32 short answer questions.

In these creative hands-on activities, students construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....

Students identify the different types of mixtures. They identify examples of solutions, suspensions, colloidal dispersions, and emulsions through a game and basic experiments.

In this equilibrium learning exercise, students read about phase equilibrium and dynamic equilibrium. They answer nine questions based on their reading and their background in chemistry.

Students explore polymer properties. In this instructional activity about polymers, students perform an experiment to understand polymers, their properties, and that they are formed from small molecules. Students role play pretending...

Students explore the genetic engineering of food.  In this health lesson students explain how DNA technology can be used to produce food. 

Fourth graders use mucilage glue and magnesium sulfate to make crystals. They mix the ingredients, place a drop on a glass slide and observe the forming crystals.

Students study the changes in land formations caused by water erosion. They work in groups to build a model of a mountain composed of materials that will best withstand water erosion.

High schoolers describe the Le Chatelier Principle. They participate in an experiment in which they observe the changes in an equilibrium system. They answer discussion questions to end the lesson.

In this chemistry worksheet, students write the balanced equation for the reaction and rearrange the potassium expression to solve for x. Then they determine how many grams of silver chromatic can dissolve in a specified amount of sodium...

Students develop a better understanding of the need to conserve our renewable resources.  In this water cycle instructional activity students take notes, complete a guide sheet and illustrate the water cycle. 

Students study disease and explore  how it can be avoided or treated with simple solutions.  In this investigative lesson students create a food chart for two weeks for themselves to track and be sure they are getting all the...

Young scholars observe crystals under the microscope. In this science activity, students compare how the crystal look like using their eyes, hand lens and microscope. They identify the type of crystal based on the amount of light they...

Students investigate the impacts of major rainfall and subsequent runoff on turbidity in lakes. They, in groups, develop a presentation of their research and/or write a paper summarizing their investigation.

Ninth graders investigate relationship between the temperature and concentration of dissolved oxygen in water. They examine how pollution and other natural influences can cause the parameters to change. In groups, 9th graders collect...

Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson plan, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
